Abstract

Uso de una membrana en un motor de combustión interna con ignición por chispa, para segregar un primercombustible que tiene un número de octano Research (RON) mayor que 100, una tasa de combustión mayor que105% de isooctano y una velocidad de llama laminar mayor que 105% de isooctano a partir de combustibles sinplomo que hierven en el intervalo de la gasolina y formar un segundo combustible que tiene un RON menor que 90,una tasa de combustión mayor que 105% de isooctano y una velocidad de llama laminar mayor que 105% deisooctano, definiéndose la tasa de combustión de los combustibles primero y segundo como 1/ángulos de cigüeñal para 90%de combustión completa y midiéndose en el momento del ciclo operativo del motor que corresponderespectivamente a condiciones distintas de carga baja y condiciones de carga baja, midiéndose la velocidad de llama laminar del combustible primero y segundo a una temperatura y presiónrepresentativas de las condiciones en el motor, respectivamente en condiciones distintas de carga baja y encondiciones de carga baja, siendo las condiciones de carga baja aquellas regiones del mapa de operación del motor a o por debajo de aquéllasen las cuales el motor puede hacerse funcionar con un avance de encendido mínimo para reglaje óptimo del par detorsión (MBT) con un combustible que tiene un RON de 90 sin la condición de detonación.Use of a membrane in an internal combustion engine with spark ignition, to segregate a first fuel that has a Research octane number (RON) greater than 100, a combustion rate greater than 105% isooctane and a laminar flame velocity greater than 105% isooctane from sinplomo fuels that boil in the gasoline range and form a second fuel that has an RON less than 90, a combustion rate greater than 105% isooctane and a laminar flame velocity greater than 105% deisooctane, the combustion rate of the first and second fuels being defined as 1 / crankshaft angles for 90% of complete combustion and measured at the time of the engine operating cycle corresponding respectively to different conditions of low load and low load conditions, measured the laminar flame speed of the first and second fuel at a temperature and pressure representative of the conditions in the engine, respectively e under different conditions of low load and low load conditions, the low load conditions being those regions of the engine operating map at or below those in which the motor can be operated with a minimum ignition advance for optimum torque adjustment detortion (MBT) with a fuel that has a RON of 90 without the detonation condition.
